Frak! - Swear word used by pilots
aboard the gigantic spacecraft Galactica on the science fiction
series BATTLESTAR GALACTICA/ABC/1978-80.

When frustrated or mad Lt.
Starbuck (Dirk Benedict) was often heard mouthing this futuristic
"cuss" word. Another foul phrase used was “Feldercarp.”

In the 2004 series remake, the scriptwriters continued to
use the word “Frak.” It is strange that the word we substitute for
“Fuck” is acceptable even though we know that it expresses the same
sentiment and meaning. So an actor can safely say, “What the frak”
or “Frak you” but he can’t say the real “F” word on the air. That’s
just so “Fraken” hypocritical.

Admiral Cain:

[Tortured by Cain, Number Six now holds a gun to her head] Frak
you!

Number Six:

You're not my type. [shoots Cain]

Doctor Gaius Baltar:

Well, quite frankly, I don't
give a flying frak whether you believe me or not, all right?
Because I've had it, I am...I'm tired of being pushed and
prodded around like I'm some kind of toy. I'm not your
plaything!
